HELP!!!

HAD A SPRINKLER GUY COME OUT AND TURN OUR AND HAD HIM SET THE TIMERS. ALL OF THEM WERE WORKING, NOW STATION 3 IS NOT WATERING, I'VE TRIED STARTING MANUALLY AND THERE IS NO WATER COMING OUT.. CAN'T SEEM TO FIGURE IT OUT! ANY HELP IS APPRECIATED!!!!

Manually as in "at the controller" or as in "at the valve."
If you haven't tried the valve yet that is your next step.

Or get a multimeter and see if the controller is putting 24v to zone 3. Set the mulitmeter to volts. Place one probe on the COM screw and the other on the zone 3 screw. Should read 24 volts, +/-. If not you may have a bad controller.
